Problem: Link Failures

A link failure typically appears as a period of consecutive packet loss
that can last for many seconds, followed by a change in delay after
the link is re-established.

Link failures can be caused by equipment problems (e.g. a failed âbladeâ
in a switch or router, power failureâ¦), a cable being unplugged or cut,
a configuration change in the transport network or potentially a denial
of service attack. Routers are generally intelligent enough to recognize
a link failure and find an alternate route.

Impact

Link failure will result in significant gaps in
received speech. It is unlikely that link failures will occur frequently
however they could potentially last for several seconds.

Resolution

Regular occurrence could be symptomatic of equipment or power supply reliability
problems. Use traceroute to determine the point at which link failures
are occurring.
